Those who are concerned about conflict between Israel and Iran will be against this treaty. I think that more neighboring middle eastern nations would be publicly expressing concerns.  Pretending things are okay is a policy of this administration. They are proclaiming it a great success and taking positive headlines. But for me it is giving more time and hence the possibility Iran can make that bomb. The review in 6 months is going to be awkward as I am sure that Iran has prepared a way to defend any new progress.  Giving Iran relief from Sanctions and billions of dollars held mostly in the EU is giving them too much before there is evidence or any cutting back on their drive for nuclear defense efforts.  Looking the other way and attempting to hide the Benghazi "massacre" facts is a very factual example of such an approach. Pretending that this treaty will stop Iran from developing nuclear bombs is another shame on America.
